    An element Y emits one \[\alpha \]-and two \[\beta \]-particles to give X. X and Y are:

    A)  isotones                             

    B)  isobars

    C)         isotopes        

    D)         isoelectronics

    Correct Answer: C

    Solution :

    Let atomic mass and atomic number of Y are a and b respectively. Hence, \[{}_{b}{{Y}^{a}}\xrightarrow{-\alpha }{}_{b-2}{{M}^{a-4}}\xrightarrow{-\beta }{}_{b-1}{{N}^{a-4}}\xrightarrow{-\beta }{}_{b}{{X}^{a-4}}\] Hence, X and Y are isotopes (i.e., having equal atomic number but differing in mass number)
